Steps in Replication

1. Conversion into dsDNA (=host repair process?)

2. Early transcription (by host enzymes)

3. Translation of (regulatory) protein and "rolling circle" ssDNA replication

4. Late transcription (usually mediated by viral proteins)

5. Synthesis of late (=structural) proteins

6. "Sequestering" of viral genomic ssDNA

7. Assembly into virions
